Demand the highest level of efficiency, quiet operation and durability from your aquarium pumps. ReeFlo Hybrid Pumps are designed to power and grow with complex aquarium setups without compromising flow rate. High-efficiency external pumps convert to more powerful models with included impeller kit. Buy ReeFlo Hybrid Pumps once and simply convert them as your aquarium needs grow!

Premium ReeFlo Hybrid Pumps boast cooler, quieter operation while drawing less energy. High flow, low wattage water pumps are designed for long-lasting, reliable use great for custom freshwater or saltwater aquariums setups. Made in the USA. 5-year warranty.

Do not submerse the unit in water. It is not a submersible pump. Do not allow the pump to be submerged or otherwise get wet.

Locate the pump as near the source to be pumped as possible. A flooded suction is preferred.

The pump is not self-priming. Therefore, if the fluid level is below the pump, a swing-type check valve or a foot valve must be installed below the water level. The pump and inlet line must be primed prior to start up. DO NOT run the pump dry.

Mount the Motor Base to a secure, immobile foundation preferably one that will dampen vibration.

Use only plastic fittings on both the inlet and discharge ports. Seal the inlet and discharge fittings with Teflon® pipe dope. These fittings should be self-supported and in neutral alignment with each port, (i.e. Fittings must not be forced into port alignment, which may cause premature line failure or damage to the pump volute).

Never restrict the inlet. Keep inlet line as free of elbows and valves as possible. Always use pipe of adequate diameter. This will reduce friction losses and maximize output. Never use an inlet line of smaller diameter than the discharge line. Minimize the suction lift.

Tips & Troubleshooting
ReeFlo hopes you will find the following suggestions and comments regarding pump installation to be helpful. ReeFlo does not claim that any of these suggestions are the only way to accomplish your job, but in general, they will solve many of the commonly found problems and help you prevent many others.

Please note that ReeFlo pumps are external pumps. Do not submerge!

Locate the pump as close to the source as possible. It is best to have your main (longest) run of pipe on the discharge side of the pump. The pump is designed to push water, not pull it.

Never run a pump dry. This may damage the mechanical seal and impeller. They are designed to pump fluid, not air. Insure the pump is full of water before you turn it on, and that it doesn't out pump the supply.

If your pump is producing too much flow, you can reduce the flow by partially closing a valve on the discharge line. Never restrict the inlet!!! Surprisingly, this will make the motor work less and use less electricity! This "valving back" simply causes the pump to operate further back on its performance curve.

If your pump is not producing enough flow, the easiest step is to widen the line especially on the intake. The narrowness of the line has great bearing on friction loss.

If more flow is required than a single pump can produce, consider using two or more pumps in parallel. By doing so you will double the flow. If more pressure is required, consider using two pumps in series (one feeding into the other). This will have the effect of doubling the pressure. Using two pumps instead of one larger pump uses an average of 30% less electricity.

Choose a pump that can give you the required flows at the lowest possible power consumption. Since pumps often operate continuously, the power consumption (watts - not amps), and its effect on your monthly utility bill can be very significant.

Check to be sure the motor electrical connections are set up to match the supply voltage.

Install shut off valves before and after the pump, so you can easily remove it from the line without having to drain your system. Be sure to use ball valves, as they have low friction loss characteristics.

Use Teflon® paste (not tape) for sealing threaded joints.

Make sure all your pipe joints are airtight. This is especially important on the suction side.

When choosing a water pump type and size, there are several factors to include in your decision. Filtration type, desired flow rate, plumbing and head height, and adding additional devices all come into play. This article helps clear the confusion.

Your primary objective is to maintain a healthy thriving aquatic environment for your underwater plants and animals. To achieve this goal, one of the most critical decisions you'll make is choosing the right pump. Compare pumps here.

Great Pump, runs warm
This external pump was a major change for my 180 gal. marine tank, removing two large submerged "Lifegard Quiet One" pumps in an attempt to lower water temp in system. That wasn't achieved even after adding a 5" Orion fan to blow air through the separation of motor and pump. Need to add a chiller. Still, a great pump, greatly increasing flow in a tank with lots of gorgonian corals. Quiet, makes less noise than protein skimmer.
